scaremongering | ☣cr and plotting

If you could, please let me know which, if any, of the following would be okay by you (please include character and journal names if answering for more than one in a comment):

Can he verbally psychoanalyze your character, e.g. turn bits of conversation into mini-therapy sessions?
Can he fear gas your character?
If yes to number two, is it okay for him to set up character-specific fear scenarios?
Would you be interested in using your character as a research specimen?

If there is anything in particular that you'd like to play out with the good doctor or his alter-ego, drop me a line here!
